Using the following autoinstall configuration for disk layout:

storage:
    layout:
      name: direct

the installer stalls on:

...
start: subiquity/Filesystem/_probe:
start:  subiquity/Filesystem/_probe/probe_once: restricted=False

And hangs forever.

Assuming this is a simple disk layout i would like to think that there should not be any issues.

Running lsblk results in a disk sda with no partitions. Secureboot and security chip is disabled.

I have ran the same autoinstall configuration on multiple Lenovo Thinkpad L460 with updated bios and some of them stalls, and some of them don’t.
